A simple, rapid, and sensitive point-of-care (POC) device for the on-site detection of doxorubicin was developed. The proposed method relies on the naked-eye detection of the intrinsic fluorescence of the drug in a lateral flow device (LFD) configuration, exploiting the biological recognition of DNA probes and avoiding the use of expensive antibodies and sophisticated instrumentations. The POC assay does not require any pre-treatment or purification step and provides an immediate visual readout, achieving a limit of detection as low as ca. 1 ng doxorubicin, outperforming several laboratory-based instrumental techniques. The POC method was proven useful for the detection of trace amounts of the drug both in the case of water solutions (to simulate surface contaminations) and in urine samples, opening promising perspectives for routine monitoring of doxorubicin, with potential benefit to healthcare workers and personalized chemotherapies.

Traditionally, clinical devices are designed, tested and improved through lengthy and expensive laboratory experiments and clinical trials [1]. More recently, computational methods have allowed for rapid testing, speeding up the design process and enabling far more complete searches of design space. While computational models cannot fully capture the complexities of biological systems, they provide valuable insights into crucial underlying mechanisms, such as the effects of fluid-structure interactions (FSIs).

Carotid-cavernous fistulas (CCF) are indirect or direct vascular shunts between vessels of the cavernous sinus and the carotid artery. While indirect CCFs have high rates of spontaneous resolution, direct CCF cases can result in significant orbital and neurological sequelae. This case describes a 75-year-old male patient presenting with acute subarachnoid hemorrhage secondary to a Barrow type-D CCF.

Congenital syphilis is a preventable yet severe condition resulting from untreated maternal syphilis. Since 2016, Australia has recorded over 95 congenital syphilis cases, with 31/95 (33%) associated with perinatal death. Syphilis serology is complex and therefore performed in designated central laboratories.

Colloidal gold technology has revolutionized viral diagnostics through its rapid, cost-effective, and user-friendly applications, particularly in point-of-care testing (POCT). This review synthesizes recent advancements, focusing on its role in detecting respiratory viruses, hepatitis viruses, and emerging pathogens. The technology leverages the unique optical and physicochemical properties of gold nanoparticles (AuNPs), including localized surface plasmon resonance (LSPR) and high surface-to-volume ratios, to achieve rapid antigen-antibody recognition with visual readouts within 15 min.

A series of molecular logic gates with multiple biocomputing capabilities have been successfully fabricated by using four antibiotic residues [tetracycline (TET), chloramphenicol (CHL), kanamycin (KAN), and streptomycin (STR)] as inputs. The lateral flow strip biosensor was utilized to realize the visual and portable sensing of logic events. Four basic logic gates (OR, AND, XOR, and INHIBIT) and three cascade logic circuits (OR-INHIBIT-AND, 3AND-OR, and XOR-INHIBIT-OR-AND) were constructed.
